COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 707,914, dated August 26, 1902. Application iiled March 31, 1902. Serial No. 100,808. (No model.)

To all whom t may concern:

Be it known that I, VLLLIAM T. GATES, a citizen of the United States, residingat Simpson, in the county of Taylor and State of West Virginia, have invented a new and useful Coke-Oven, of which the following" is a specification.

This invention relates generally to cokeovens, and particularly to that class known as bee-hive ovens.

The object of the invention is in a ready, simple, thoroughly feasible, and practical manner to utilize the heat from the oven producing furnace-coke for doing effective work in the oven producing foundry-coke.

A further object is to facilitate handling the finished coke.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in arranging the forty-eight-hour or furnace-coke-preducing oven on a plane below that occupied by the seventy-twdhonr or foundry-colie-producing oven and in directing the heat from the forty-eight-hour oven into and beneath the iioor of the seventytwo-hour oven, and thence entirely around the lower portion of the side walls f thereof.

The improvements hereinafter described are equally adaptable to seventy-two-hour ovens having either single or double walls, the result being eected in the former case by providing externally-arranged fines around the lower portion of the oven to receive the heat from the forty-eight-hour oven and in the latter case by providing an internally-arranged flue between the walls of the lower portion of the oven.

The invention consists,further,in the novel construction and combination of parts of a coking-oven, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there are illustrated two formsof embodiment of the invention, each capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to 'of the apparatus.

shape, proportion, and exact manner of assemblage without departing from the Spirit thereof, and in the drawing Figure 1 is a view in vertical transverse section through a coke-oven embodying the essential features of this invention. Fig. 2 is a view in horizontal section, taken on the line 2 2, Fig. l, and looking in the direction of the arrow thereon. Fig. 3 is a view in horizontal section of a slightly-modified form Fig. L is a transverse Seotional view of a slightlynnodied form of seventy-two-hour o ven.

As is well known, ovens of this character are generally built with their floors disposed practically on the same plane. the ovens according to the present invention they are erected back to back in blocks, with their oors on different planes, as clearly shown in Fig. 2, wherein two of each of the ovens are exhibited, it being understood that this number may be increased at will and still be within the scope of the invention.

The forty-eighthour or furnace-coke-producing oven 1 is of 'the usual or any preferred construction and has its ioor disposed any desired distance below that of' the seventytwo-hour or foundry-coke-producing oven 2, which latter may also be of the usual or any preferred construction. In the arrangement of this latter oven, as shown in Figs. l and 2, its lower wall is double, as at 3, and is spaced from the archwall to present an annular ue 4, which communicates withatortuons duct or i'lue 5, opening into the forty-eight-hour oven at any preferred height above its bottom, as at 6. These ovens are housed in suitable masonry, comprising battens 7, a larry-pillar 8, having the usuallarry-tracks 9, and between the battens and the larry-pillar' and beneath the floors of the ovens is interposed the usual filling 10 and l1. improvements hereinafter pointed out, the exact construction of the ovens and theirsupporting masonry is immaterial and may be of any preferred style. The forty-eight-hour oven is provided with theusual charging-nue 12, closed by av damper or cover 13, and the seventy-tWo-hour oven is provided with a chargingilue 14, normally sealed by a closure In building Aside from the particular IOO 15. (Indicated by ,dotted lines in Fig. 1.) Each oven is also provided with a door 16 and 17, respectively, of the usual or any preferred construction, and with an apron 18, arranged immediately under the oven-door sills and constituting slides for directing the coke to conveyers 19, to which they are hinged, the conveyers being disposed entirely around the blocks to transport the coke to cars, furnaces, or to receiving-bins. The tortuous duct 5, connecting the forty-eighthour oven with the seventy-two-hour oven, may be made of any suitable material capable of withstanding a high degree of heat, preferably of vitried clay, and is to be disposed under the tile floor of the oven in such manner as to heat its entire area evenly, the duct to be either circular or square in cross-section, as may be preferred. The highly-heated products of combustion from the forty-eight-hour oven enter the duct 5, traverse the same, and escape into the iiue 4 at the left-hand side of the door 16, thence around the flue and escape therefrom at the right-hand side of the said door, and thence into the oven. It will be understood, of course, that the points of entrance and escape of the products may be the reverse of that just described-that is to say, they may enter at the right-hand side of the door and escape at the left-hand side. The iiue 4, except at its discharge end, is closed by a cap 20, clearly shown in Fig. 1, thereby to compel the heated products of combustion to traverse the entire circumference of the oven before escaping. Where the seventy= two-hour oven is constructed with al single wall, as shown in Figs. 3 and et, the duct 5 is disposed in the same manner, or substantially so, as shown in Figs. 1 and 2; but its discharge end projects through the wall of the oven at 2l and is connected with a flue 22, that encir cles the lower portion ofthe oven in as many coils as desired and enters the oven at 23, a valve 24, disposed on the flue adjacent to its point of connection with the oven, serving to control the passage of heated products thereto. To prevent radiation of heat from the flue 22, the same is embedded in a suitable lling 25. Whether the seventy-two-hour oven be heated internally only by the heated products of combustion from the forty-eight-hour oven,as shown in Figs. 1 and 2, or is internally and externally heated by said products, as shown in Fig. 3, the object sought is attained in a thoroughly practical and economical manner, and owing to the fact that products heretofore generally wasted are utilized for doing effective Work it will be seen that a large saving in the production of coke of the characters specified will result.

It is to be understood that the invention is not to be limited to the precise construction and arrangement of the duct 5, as shown, nor to the exact point of location at which it is associated with the forty-eight-hour oven, as

it will be obvious that changes may be resorted to in carrying into eifect these parts of the invention without departing from the spirit thereof.
